External Error: invalid stored block lengths

[affinity]

Has anyone got this message while trying to import a backup?

Seams to be only affecting one app in my system but nonetheless not sure what may have caused this error, I have since backed up to a version 2 weeks ago but after that point the backups seem to fail. I need the data that was created inside since then but cant get a working restore after that point. Any thoughts?

Wordpress v2.25.0

@affinity which backup provider are you using? This is an error from the service.

@girish It's a CIFS mount from another local Linx server.

@affinity it seems to me that the backup file is corrupt (the error comes from gzip, I think). Not sure where the CIFS target is but I would check if the disk of that server is doing ok . Do you have any other (older or newer) backups to work with?

@girish I think this could be the case, I tried to extract the Gzip and tar file inside but had an extraction failure, So I think the file may have been corrupted due to a faulty sector of the drive. Going to replace it shortly.

No, I didn't have any other redundancy. But hey, it happens.

@affinity yes, so in coming releases, we will have a checksum to verify backups. Hopefully, this is caught sooner and not just when trying to restore.
